AbstractIn this paper, the effect of hydrostatic pressure on the corrosion behaviors of two steels was investigated by weight loss test, electrochemical measurements, rust layer analysis and morphology observation in natural seawater environment with high-pressure in lab. The results showed that X steel was inclined to being corroded. With the increase of hydrostatic pressure, the corrosion resistance of two steels were deteriorated, which were attributable to the increase of the anodic reaction rate. Hydrostatic pressure had little effect on oxygen diffusion reduction process of X steel. However, the cathodic current density of Y steel under higher hydrostatic pressure decreased because the corrosion products were directly involved in cathodic reduction reaction. And with the increase of hydrostatic pressure, the morphology of two steels changed significantly and differently. Under high pressure, some shallow-dish shape localized corrosion appeared on the surface of X steel, whereas on the surface of Y steel some tunnel localized corrosion appeared.
